[okl4-developer] Starting 2 OKLinux instances with LCD

[Damien Schulz]

Hello,

after having written a little procfs module to communicate with L4 services (thanks to Jorge), I'm now trying start 2 OKLinux instances on a Neo-1973 GTA01bv04 platform - both with access to the LCD driver. It would suffice if the fastest of both linux instances writes to the LCD (first come, first serve), but it's not possible to start 2 OKLinux instances with LCD enabled.

This is the error message that is shown:
>  igms0:Iguana virtual frame buffer driver v1.0
> Iguana virtual serial driver v1.0
> NET: Registered protocol family 2
>  unknown partition table
> roottask read pagefault at 32e6a004, ip=0010834c - deny
> --- KD# roottask pagefault  ---

If I disable the LCD driver for the second linux instance, it works. Any idea that could help here?

Thanx in advance,
~Damien
